The circular portion may be arranged in proximity to the compressor at around a compressor inlet. The passageway may be divided at least circumferentially and radially across the entire elongated portion and at least partially across the circular portion to configure a plurality of flue gas and air inlet segments for respectively conveying flue gas and air streams therethrough. The flue and air gas streams from each of the respective plurality of flue gas and air inlet segments, converge to be blended into a target mass stream for being conveyed into the compressor.

Abstract: A method for operating a gas turbine system in part load operation wherein a compressor pre-guide blade adjustment for part load operation is initiated in case of a given state of a flow medium which flows into a compressor, a value of the initiated compressor pre-guide blade adjustment is compared with a compressor pre-guide blade adjustment limit value which is determined depending on the state of the flow medium, and, if the value of the initiated compressor pre-guide blade adjustment meets a predefined condition with regard to the compressor pre-guide blade adjustment limit value, at least one measure is initiated for changing the state of the flow medium which flows into the compressor in part load operation. An arrangement has an actuating device, determining device and control unit to carry out the method. The gas turbine system has an anti-icing device and/or an intake air heating device and the arrangement.

Abstract: The present invention is a prime mover with recovered energy driven compression for stationary and motor vehicle application. Efficient low compression operation, especially beneficial to small gas turbines, is enabled with either ambient or cryogenic intake air. Recovered energy, liquefied air cooling and re-liquefaction of air by a cryogenic sink minimize motive fluid compression work of a jet compressor driving exhaust gas recirculation. Regenerative heat exchanger terminal temperature difference relative to turbine temperature drop and heat exchanger surface area are reduced.

Abstract: Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.
